Abstract
Thermal transport is an increasingly important experimental approach to probe extraordinary physics in strongly correlated quantum materials. In recent years, many unexpected magnetothermal transport signatures have been observed including large thermal Hall effects in a few important insulators (e.g., SrTiO3 and La2CuO4), creating puzzles in the community. In this talk I will show that the key to these puzzles lies on the phonons and how they respond to magnetic field efficiently. I will also discuss possible mechanisms underlying these experimental observations and picture future directions towards probing exotic phases of matter through analyzing thermal transport in a more revealing manner.
Biography
Dr. Xiaoqi Sun is currently a postdoctoal researcher at the Max Planck Institute of Quanutm Opics. He was a Gordon and Betty Moore Postdoctoral Scholar at the Institute for Condensed Matter Theory at the University of Illinois at Urbana-Champaign from 2020 to 2023, and obtained his Ph.D. in physics at Stanford University in 2020. His current research interests involve topological phenomena out of equilibrium, dynamics and transport in quantum materials, and interdisciplinary studies at the intersection of many-body physics, machine learning and quantum information science.
